Access rights to another participant’s foreground or background are only to be granted if they are needed in order to carry out the project (for its implementation) or to use one's own foreground.
Access rights needed in order to implement the project shall be granted at least until the end of the project, even by the participants that leave the project before its completion.
However, access rights for use purposes of foreground (exploitation and further research) may be granted up to one year after the end of the project or the termination of the involvement of a participant in a project.
Note that the actual duration of such access rights might be negotiated by the participants concerned and agreed differently (e.g. shorter, longer period or for instance, it might be extended until the expiry of a patent).
